In wake of the disaster, the Japanese government raised the annual acceptable level of radiation from 1 millisievert to 20 millisieverts, which raised concerns for the health of residents.

Baskut Tuncak, the U.N. special rapporteur on hazardous substances, claims that radiation levels remain unacceptably high in Fukushima, and has thus criticised the government’s move to remove all evacuation orders within the next five years.

In response, Japan’s government refuted the statement and dismissed his claims as fanning “unnecessary fears” about Fukushima.
